It is difficult to distinguish the sand layer 19 under the snow layer from the snow layer 4 in terms of color.
Compared with the frozen layer,
The marker 20 having a color other than white as the depth indicator
The snow layer 4 is scraped off because the
Is near the surface of the frozen sand layer 19 and the artificial snow is supplemented.
It is said that colors other than white have been reached,
Exposing the marker 20 allows easy recognition in a white environment.
I know it.
